A summary of relative ages of lunar nearside and farside plains
Joseph M. Boyce, Arthur L. Dial, Laurence A. Soderblom
1975, Open-File Report 75-141
This report contains a summary of the moon-wide distribution of relative ages of lunar plains units determined with Apollo and Lunar Orbiter photographs. Relative ages are expressed as the largest diameter of craters (DL, meters) in a mappable unit that are eroded to a slope of 1° by the net...
The geologic story of Isle Royale National Park
N. King Huber
1975, Bulletin 1309
Isle Royale is an outstanding example of relatively undisturbed northwoods lake wilderness. But more than simple preservation of such an environment is involved in its inclusion in our National Park System. Its isolation from the mainland provides an almost untouched laboratory for research in the natural sciences, especially those studies...
Reconnaissance geology of the Central Mastuj Valley, Chitral State, Pakistan
Karl W. Stauffer
1975, Open-File Report 75-556
The Mastuj Valley in Chitral State is a part of the Hindu Kush Range, and is one of the structurally most complicated areas in northern Pakistan. Sedimentary rocks ranging from at least Middle Devonian to Cretaceous, and perhaps Early Tertiary age lie between ridge-forming granodiorite intrusions and are cut by...
Hydrologic reconnaissance of the Montezuma Creek-Aneth area, southeastern Utah
C. T. Sumsion
1975, Open-File Report 75-268
The Montezuma Creek-Aneth area is in the northeastern part of the Navajo Indian Reservation in southeastern Utah. It is a semiarid area along the San Juan River near the communities of Montezuma Creek and Aneth. Within the Blanding Basin, geologic formations exposed are of Jurassic and Quaternary age. The rock...
Maps showing drift patterns along the north-central Texas coast, 1973-1974
Gary W. Hill, Louis E. Garrison, Ralph E. Hunter
1975, Miscellaneous Field Studies Map 714
An investigation of the rates and directions of drift in the northwestern Gulf of Mexico was initiated in January 1970 as part of a program to study depositional processes and sediment movement off the southern Texas coast. The first phase of that program, a study of coastal drift off south...
Summary of floods in the United States during 1969
J.K. Reid
1975, Water Supply Paper 2030
The most outstanding floods in the United States during 1969 are described in chronological order. The areas most seriously affected by flooding were: Central and southern California (January and February); the upper Midwestern States of North Dakota, South Dakota, Minnesota, Iowa, Wisconsin, and Illinois (April); north-central Ohio (July); Mississippi, Alabama,...
Digital models of a glacial outwash aquifer in the Pearl-Sallie Lakes area, west-central Minnesota
S. P. Larson, Mark S. McBride, R. J. Wolf
1975, Water-Resources Investigations Report 75-40
-p^e need for study of lake-ground-water interchange has been accentuated by eutrophication of lakes in the Pearl-Sallie Lakes area of west-central Minnesota. The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at...
Analytical data for geologic units in Missouri and parts of Kansas, Oklahoma and Arkansas
Josephine G. Boerngen, George Van Trump, Richard J. Ebens
1975, Open-File Report 75-137
This report lists the geochemical data collected during the course of a reconnaissance study of compositional variation in the bedrock and surficial gelogic untis exposed in Missouri and adjoining parts of Kansas, Oklahoma, and Arkansas.  The primar object of the study was to assess scale-related components of geochemical variance with...
A program for mass spectrometer control and data processing analyses in isotope geology; written in BASIC for an 8K Nova 1120 computer
J. S. Stacey, J. Hope
1975, Open-File Report 75-127
A system is described which uses a minicomputer to control a surface ionization mass spectrometer in the peak switching mode, with the object of computing isotopic abundance ratios of elements of geologic interest. The program uses the BASIC language and is sufficiently flexible to be used for multiblock analyses of...
A review of recently active faults in Taiwan
Manuel G. Bonilla
1975, Open-File Report 75-41
Six faults associated with five large earthquakes produced surface displacements ranging from 1 to 3 m in the period 1906 through 1951. Four of the ruptures occurred in the western coastal plain and foothills, and two occurred in the Longitudinal Valley of eastern Taiwan. Maps are included showing the locations...
Prediction of maximum earthquake intensities for the San Francisco Bay region
Roger D. Borcherdt, James F. Gibbs
1975, Open-File Report 75-180
The intensity data for the California earthquake of April 18, 1906, are strongly dependent on distance from the zone of surface faulting and the geological character of the ground. Considering only those sites (approximately one square city block in size) for which there is good evidence for the degree of...
